How much has Revolution Wind stop-work order cost Orsted?

Stop-work order on major offshore wind farm project has been lifted, but not after a delay resulting in considerable delay costs for developers Orsted and Skyborn Renewables

A month after Orsted’s worst nightmares were realised with the stop-work order on Revolution Wind, it has won a court ruling allowing it to get work underway again on the project. But how much has the damaging delay already cost the Danish developer?

Orsted has not had much good news out of the US this year, but there will have been celebrations in Copenhagen yesterday after a federal court granted a preliminary injunction lifting the stop-work order.
The Trump administration hit the 704MW offshore wind array with the order on 22 August. The project was by that stage already 80% built, with 45 of the total 65 Siemens Gamesa turbines already installed.
The US District Court for the District of Columbia’s 22 September order allowing construction to resume comes 31 days after it was brought to an abrupt halt by the US President’s offshore wind hit squad.

So how much will the order have cost Orsted in that time? Not to mention its joint venture partner Skyborn Renewables – a German subsidiary of Global Infrastructure Partners – that owns a 50% stake in the project.

In the wake of the stop-work order being issued, analysts estimating how much it could cost the project referred to the example of Empire Wind. That 810MW offshore wind project, which is being developed by Norway’s Equinor, was also subject to a stop-work order earlier this year.
Equinor’s chief financial officer estimated the oil giant was “burning $50m a week” on Empire Wind while it was on hold. Incidentally, that stop-work order was in place for a similar amount of time, having been imposed on 16 April and lifted 33 days later on 19 May.
Orsted estimated in its investor prospectus last week that for each week the Revolution Wind stop-work order remained in place, it would incur recurring additional costs of around $15m “based on current assumptions” for the project.

If the order continued after “late September,” Orsted said it could “incur significant additional costs of an uncertain amount,” a fate it appears to have narrowly avoided with yesterday’s ruling.

The $15m figure accounts for only Orsted’s half of the project costs, giving $30m as the total delay cost for the project on a weekly basis.

That figure, if counting from the day the stop-work order was issued (albeit it came relatively late on a Friday) would put the delay cost for Revolution Wind at around $133m – $66m each for Orsted and Skyborn.

Unfortunately, the story does not end there for Orsted. This is due to the knock-on effects the Revolution Wind stop-work order had on its neighbouring 924MW Sunrise Wind array. Orsted — much as it would prefer not to — owns Sunrise in its entirety.

This knock-on is due to the fact the projects are using many of the same vessels.

Orsted warned in its investor prospectus last week that each day the Revolution stop-work order remains would result in a “corresponding day’s delay” to turbine installation at Sunrise, which will delay the start of revenues from the project.

Analysts had raised the question of whether Sunrise, which is behind Revolution in its construction schedule, could use some of the vessels to carry out work when they would otherwise be idle, saving costs.

Orsted said in its prospectus, published weeks after the stop-work order was implemented, that it was “uncertain” whether it will be able to redirect vessels to Sunrise, which doesn’t necessarily give confidence to the idea that it had managed to achieve this, certainly to a great extent, in the interim period.

Orsted has estimated that, for each week the stop-work order was in place, it will result in a future cost of $10m for Sunrise Wind “due to knock-on delays.”

Again, calculating based on stop-work order lasting 31 days, that comes to a future cost of $44m – solely for Orsted on this occasion.

That would put the total cost of the stop-work for Orsted at roughly $110m.

And that is assuming Orsted is able to get work underway today, which is not necessarily a given. Orsted said in its statement yesterday that Revolution Wind will “resume impacted construction work as soon as possible,” declining to provide any further detail when approached by Recharge.

Clarksons Securities, in its own analysis, also concluded that the “incremental cost” of the stop-work order “may have already surpassed $100m”.

Aside from the direct additional construction costs, the delay will also potentially push back Orsted cashing in on PPA revenues from Revolution Wind and Sunrise, assuming it is not able to somehow make up some of the lost time.

It is also not clear if Orsted has factored in the legal costs of fighting the stop-work order in court to its calculations. Revolution Wind has retained leading US law firm Latham & Watkins to fight the case, which remains ongoing, with any ruling of the DC district court open to appeal, as the billable hours mount up.

Orsted may have won the battle, but a costly war with the Trump administration is far from over.
